While road tubeless is still slowly gaining in popularity, there are still a lot more bikes out there that run tubes. And for those that are willing to spend a little more for a better tube, Biketube has a new premium option.
Their new Butane Black performance series tubes use a 0.73mm butyl rubber wall which essentially makes it a thinner and lighter tube than standard (0.9mm). Biketube claims that this thinner material also helps to decrease rolling resistance.
It also includes a black aluminum valve stem with a removable valve core. Together, the thinner rubber and aluminum valve add up to a 20g weight savings per tube.
Offered in 48, 60, and 80mm valve lengths, the tubes are offered in one width to fit 23-30mm tires. Pricing starts at $10.50 for the 48mm valve, and tops out at $12.00 for the 80mm valve.
